Why did Senate Armed Services Committee Chairman, John Warner, initiate his own investigation?

Senate Armed Services Committee Chairman John Warner initiated his own investigation primarily due to concerns related to U.S. forces procedures against terrorist attacks. This interest often arises from ongoing national security challenges and the need to ensure that military strategies and actions are adequately aligned with evolving threats. Investigating these procedures allows for a thorough examination of how effectively U.S. military forces are prepared to respond to terrorist threats, which is crucial for national defense.

Such an investigation aims to identify any gaps or weaknesses in existing protocols, ensure that the military is equipped to handle these threats, and assess how operational readiness can be improved. In light of increasing global security concerns, this focus on counterterrorism reflects a proactive approach to safeguarding national interests. The other choices, while they may touch on relevant areas of military oversight, do not specifically capture the urgency and context that would prompt an inquiry centered directly on counterterrorism measures.
